BTW what is "traditional animation"?
Should have been more specific, I meant the kind as in the way television cartoons were done, where you draw every frame out by hand, using all the little tricks to speed up process, like drawing specific-body movements on a different page layered on top of current one (for instance, repeated guy walking animation armless on lower layer, with arms on another, so you dont have to redraw the whole figure if you screw up the arm gestures)on a light-box/animation-disc/whatever and etc, painfully slow, but you learn a lot doing it that way especially with regards to the rules of animation, unlike in the computer world where everythings just tweened by the PC with your little adjustments between keys to give it more flow rather the a stiff robot-like figure.
[EDIT] Should have checked out Rob's links first :P, I mean traditional in the sense like the idleworm link he posted.
With regards to your tutorial, am I to assume v2.5 doesn't have actual "bone" objects like the ones I saw in 6?
